Application filed November 10,.1910.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, BERT R. BENJAMIN, a citizen of the United States,residing at Oak Park, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Grain-Binders, of whichthe following is a specification.

My invention relates to grain binders, and in particular to mechanismfor automatically operating the clutch controlling member in a manner torelease it from engagement with the clutch pawl forming part of theclutch mechanism, as commonly included in the usual construction ofgrain binder attachments for harvesters; the object of my inventionbeing to provide a mechanism simple and strong in its construction andefficient in operation. I attain these objects by means of the mechanismillustrated in the accompanying drawings, in which- Figure 1 representsa view of a grain binder at its receiving side and having my inventionforming a part of the construction thereof; Fig. 2 represents a top planview of the lower part of the binder frame, showing the manner ofmounting the combined tripping and compressor shaft; Fig. 3 is an endelevation of Fig. 1 illustrating by full and dotted lines the differentpositions of the operative parts in their movement of binding thebundle; Fig. tis a similar view showing the position of the asso-'ciated parts of the mechanism as the bundle is being discharged; Fig. 5is a detail of the stop dog mechanism; Fig. 6 is a detail of the clutchmechanism; Fig. 7 is a detached detail, partly in section, designed toillustrate the manner of mounting the tripping slide; and Fig 8 is adetached detail illustrating the operation of the tripping mechanism;Fig. 9 is a detached detail of the tripping and compressor mechanism atthe opposite end of the frame structure from that shown in Fig. 8.

The same reference characters designate like parts throughout theseveral views.

The binder frame is one having a common form, including upper and lowerlongitudinally arranged tubular arms 1 and 2, respectively, that areconnected by means of a hollow head piece 3, and 1 a transverselyarranged arm integral with arm 2 and to which is secured alongitudinally arranged tubular frame member 5 that is supported at itsforward end by means of an ear 6 integral with the lower end of the headpiece and a bracket 7, having a bearing 8, in which is journaled one endof a shaft 9, having its opposite end journaled in a bearing 10 at thelower end of the head piece.

11 represents a bracket secured to the frame member 5, and 12 a multiplecrank shaft forming part of the grain packing mechanism, journaled inbearings 13 and 14 forming part of brackets 11 and 7, respectively, theshaft being driven by means of a pinion 15 secured to shaft 9, andmeshing with apinion 16 secured to shaft 12.

17 represents the needle shaft journaled in arm 2, having a needle arm18 secured to its inner end and a crank arm 19 upon its opposite end.

20 represents the knotter operating shaft journaled in arm 1, having abevel gear wheel 21 secured to its outer end and a bundle dischargingarm 22 to its opposite end.

23 represents the knotter frame in which the shaft is journaled, 24 theknotter cam wheel, and 25 a supplemental bundle discharging arm, bothbeing secured tothe knotter operating shaft.

The shaft 9 derives motion from an operative part of the harvestermechanism by means of sprocket wheel 26, that is slidably mountedthereon, and 27 represents a rotating clutch member secured to the outerend of said shaft and adapted to operatively engage with a pinion 28loosely mounted thereon, the pinion having a pawl 29 pivotally mountedthereon and which is provided with a roller 30 that is adapted to engagewith internal teeth 31 forming part of-the clutch member 27, the pawlbeing yieldingly pressed toward the teeth, by means of a compressionspring 32, operative between the hub of the pinion and the pawl, thelatter being provided with an outwardly projecting arm 33 whereby itsmovement may be controlled. Pinion 28 meshes with pinion 34, secured tothe lower end of a shaft 35 that is journaled in the head piece 3, and36 represents a pinion secured to the opposlte end of the shaft andmeshing with the bevel gear wheel 21 secured to the knotter drivingshaft.

37 represents a crank pin secured to the wheel 21 and operativelyconnected with the crank arm 19 of the needle shaft by means of thepitrnan 38. I I 39 represents a stop dog including an arm 40 secured tothe head piece, and a depending resilient arm 41 adapted to mesh with anabutment 42 formed upon the adjacent face of wheel 21 in a manner tohold said wheel against a retrograde movement when it has reached apredetermined point in a forward direction.

43 represents a combined rocking, compressor and binder tripping shaftmounted upon the binder frame in a manner permitting it tomove bodilyaway therefrom under pressure of the grain against the binder trippingand compressor arm 44, that is adjustably secured to an arm 45 securedto the shaft. The shaft is supported at its inner end by a yoke member46', that is slidably connected with the outer end of bracket 11, thebracket being provided with an car 47, through which passes a bolt 48that is threaded intothe yoke, the inner end of the bolt beingsurrounded by a compression spring 49, that is operative between thehead of the bolt and the ear in a mannerto resist abodily movement ofthe shaft outward under pressure of the incoming grain. The opposite endof the shaft passes through a slotted opening 50 formed in an ear 51integral with the binder frame and in which the shaft may move outward,as shown by dotted lines Fig. 2.

52- represents the usual cam track upon the wheel 21, and 53 acompressor lever pivotally connected at its inner end with the binderframe and having a roller 54 jour-- naled thereon intermediate its:ends. that is adapted to engage with the cam track in a manner tocausethe opposite end of the lever, that is connected with a crank arm 55formed upon the outer end of shaft 43v by means of a link 56, to riseand fall in a manner to cause the rock shaft to rotate toward or fromthe binder to compress the bundle or permit it to be discharged in awellknownway. The movement of the shaft toward or from the binder framecontrols the clutch tripping mechanism in the following manner:

57' represents a curved clutch tripping member bent in a. mannertopartially sur round therock shaft 43, having its inner end slidablyreceived by opening 58 in stud 59, secured to the binder frame andadapted to contact with the clutch pawl arm in a trolled by the bodilymovement. of said rock 1 shaft.

of the clutch tripping member being i manner to disengage the pawl fromthe retating clutch member 27, the opposite end curved inwardly andupwardly and proresen-ts a bolt passing through an car 61', forming partof the binder frame, and the opening the tripping member, and having acompression spring 62* surrounding its upper end that isoperativebetween an ad justing nut 63 and the tripping member in amanner to. yieldingly press the shaft and tripping member in a directionto cause the latter to engage with the pawl arm and to resist bodilymovement of the shaft in an opposite direction.

64 represents a cam mounted upon the needle shaft, rotatable therewithand contacting with the tripping member, and operative to hold itdisengaged from the pawl arm until the bundle has been discharged andthe needle returned to its initial position, the cam being provided witha flange 65 that overlaps the tripping member during its operativemovement- In the operation of the machine the grain is compressedagainst the arm 44 by the packer mechanism in a well-known way until apredetermined amount is collected,

when the arm and shaft will move bodily under the continued pressureagainst the action of springs 49 and G2 in a manner to withdraw thetripping member 57 from engagement with the pawl arm 33, and the pawlthen engages with the rotating clutch member in a wellknown way and thebinder mechanism begins its cycle of movement to bind and discharge thebundle, and at theend of. the cycle the parts assume their initialposition.
